control v pastes the text getreg('+') instead of my clipboard content

[Zackhardtoname]

I have the following in my vimrc file

" C-v to paste in insert mode
inoremap <c-v> <esc>:set paste<cr>a<c-r>=getreg('+')<cr><esc>:set nopaste<cr>mi`[=`]`ia

However, I only have this problem when I use Linux and Windows. It works well on Mac OS.
